He purchased the home from TV producer Jerry Bruckheimer for a yet-to-be-revealed price. He already owned the homes on either side of Bruckheimer.

Ellison, 68, has quite an impressive real estate portfolio. This year alone he's purchased two Malibu homes and an island in Hawaii for a rumored $600 million. He also owns homes in Woodside, Calif. Newport, RI, and Kyoto, Japan.

Ellison bought this property in Woodside, Calif. for $12 million in 1995. The home is modeled after a 16th century Japanese emperor's residence. It sits on 23 acres of land and is now worth an estimated $70 million.

His most recent purchase in the area was TV producer Jerry Bruckheimer's house, which he bought this week for an undisclosed price.

Ellison is also a big fan of Lake Tahoe, where he has spent a reported $102 million buying up three separate parcels of land totaling 191 square miles. He's supposedly building an 18,000-square-foot compound on one of them.

Ellison bought Porcupine Creek in Rancho Mirage for $49 million in 2011. The 18,430-square-foot house sits on 249 acres. There's even an 18-hole golf course on the property.

Earlier this year Ellison purchased 98 percent of Lana'i Island in Hawaii. He reportedly spent $600 million on the 141-square-mile island, and plans to use it to experiment with "environmentally sound ways to live."
